Abstract

Herein we provide new information on Cnemaspis assamensis, the only species of Cnemaspis known from north-eastern India.  Based on five new samples, morphological parameters are described. The species was found to have pre-cloacal and femoral pores, not accounted for in the original description. Genetic assessment of the species was made using a 914 bp fragment of the ND2 mitochondrial gene and the species was recovered as the sister taxon of the C. podihuna clade from Sri Lanka.
